[PATCH 2/2] UBUNTU: SAUCE: drm/i915: Add second set of PCI-IDs for B43

[Ike Panhc]

SRU Justification:

Impact: Install Ubuntu Lucid on Intel B43 chipset whose PCI id is
        8086:2E90/2E92. X can not start.

Fix: Add new id 0x2E92 beside 0x2E42 for i915.ko
     Commit c96c3a[1] in mainline kernel simplies all info for each device into
     a single structure, but is landed after 2.6.36 kernel. So we still need to
     modify IS_GEN4 macro in i915_drv.h. That's why this patch does not look
     like mainline kernel one[2].

Testcase: Apply this patch on current checkout of Lucid kernel and runs with
          xserver-xorg-video-intel with the same modification, X start ok.
